Intro: Cheap Headset + Broken Cellphone = "SkypeCell"

For this first Instructable, I'll show you a recent hack I made.

I had a cheap malfunctioning headset and a broken cellphone (cracked screen) and I needed a reliable solution to make calls with Skype... so I combined two ready-for-trash items in a good SkypeCell!

Step 1: What You Need

A) If you are wealthy:

-=-=-=-=-=-=-=-=-=-=-

- A brand new cellphone with cool "calling" features: MP3, video, internet, etc.
- A brand new well-performing headset
- Some basic tools (small screw drivers, knife, soldering station, etc.)

And you will end up with a so-so quality PC phone...

A) If you are !wealthy:

-=-=-=-=-=-=-=-=-=-=-

- An old and/or broken cellphone (LG in my case)
- A cheap headset (chinese crap bought on eBay in my case)
- Some basic tools (small screw drivers, knife, soldering station, etc.)

And you will end up with a better quality PC phone :)

Step 2: Disassembling the Phone and the Headset

You'll need to completely dismount the cellphone. I used a small knife to pry the cover and to remove the small rubbers. With a Philips screw driver, I removed all the small screws. Then I forced the opening of the case with a small knife.

What you will do depends a lot on the brand and the model of your phone.

For the headset, it's really simple: just cut the two 3.5mm jack from the rest. Keep as much wire as needed. Strip of the insulators off each wire (about 2mm).

Step 3: Find the Microphone and the Speaker

First, you need to find the speaker in the phone. It's usually located near where you place your ear (what a coincidence!). Then you will find its 2 connections to the PC board.

Second, you need to find the microphone in the phone. It's usually located near where you place your mouth (another coincidence!). Then you will find its 2 connections to the PC board.

Now, you need to examine the phone to locate 1 or 2 places where you can enter the wires in the phone. I used an old tip on my soldering station to melt the case plastic, then I inserted the wires in the phone.

Step 4: Connecting the Speaker

I will assume that you now have a dismounted cellphone (PC boards exposed) and a green 3.5mm jack with 2 wires connected.

Solder the 2 wires from the plug on the speaker's PCB connections.

At this time, you can test this half-finished project by plugging in it in a PC. If you can listen phone-quality music by holding the speaker near your ear, it's good!

Step 5: Connecting the Microphone

I will assume that you now have a dismounted cellphone (PC boards exposed) and a pink 3.5mm jack with 2 wires connected.

Solder the 2 wires from the plug on the microphone's PCB connections, or directly on the mic.

At this time, you can test this almost-finished project by plugging in it in a PC. I used the free Test Call from Skype to test it. If you're able to talk and listen back, it's working.

Step 6: Completion

You can secure the connections with some electrical tape. You then need to reassemble the phone.

It sounds easy... now do it ;)

Step 7: Use It!

There is nothing more to say than: use it. You'll probably be pleased by the enhanced quality (in comparison to the original headset).

    I think it's about using the phone as a mic and speaker if you don't already have those. Perhaps you can use the speaker-phone capabilities to do it hands-free...

    I dont know whether I will be able to make it ,But was fun reading this part !HAHA:)

    i liked your idea so much i made one myself. only i used an old telephone from the thrift store. it works so good. at first i hooked up the mic wires backwards but then i turned them around and bam! it was awesome. im gonna paint the phone black now so it looks proper.

    hei i saw this Dead Ringer Head Set Hack by tk421dan , he did the exact same thing as u did. Great work guys. However i was thinking if an USB plug can be added instead of jacks into the headset. Can u guys really do that or does it needs some sort of programming?

    it wouldnt be anything to make it usb instead of the jacks. i just dont have a usb soundcard. you can add a usb soundcard in which case you would need to load the driver for it on each computer you used it with. or you can get one like this. http://cgi.ebay.com/ws/eBayISAPI.dll?VISuperSize&item=360282929503 you can also do it like this guy. https://www.instructables.com/id/USB-Phone/ i liked his usb phone i just made mine with the mic and speaker jack so it didnt need drivers other than what come with the pc that im using the phone with.

    So now I will ask the dumbest of the dumb questions, red-faced but determined: Does said dead cellphone have to have service? As in, a SIM card and a contract? Be nice, now.

    nope. In fact, you could use a house phone if you wanted. All he's doing is connecting the speaker of the phone to the green headphone plug and connecting the microphone to the red headphone plug. All the cell-phone is doing is holding the speaker and mic in place. I dont find my cell phone particularly comfortable so i'd probably use a cheapo telephone. It would be nice to get the touchpad to work, and end calls when you close the phone. Any ideas on this?

    not so much the touchpad, but to get volume and end call support you could splice an old cell with a working bluetooth headset
